Enabling/Disabling NAT (Network Address Translation)
Note:
This advanced feature should be employed by advanced users only.
Before enabling this function, MAKE SURE YOU HAVE SET THE
ADMINISTRATOR PASSWORD. Network Address Translation (NAT) is the 
method by which the Router shares the single IP address assigned by your 
ISP with the other computers on your network. This function should only be 
used if your ISP assigns you multiple IP addresses or you need NAT disabled 
for an advanced system configuration. If you have a single IP address and 
you turn NAT off, the computers on your network will not be able to access 
the Internet. Other problems may also occur. Turning off NAT will disable your 
firewall functions.
 
Enabling/Disabling UPnP
UPnP (Universal Plug-and-Play) is yet another advanced feature offered by 
your Belkin Router. It is a technology that offers seamless operation of voice 
messaging, video messaging, games, and other applications that are UPnP-
compliant. Some applications require the Router’s firewall to be configured 
in a specific way to operate properly. This usually requires opening TCP and 
UDP ports, and in some instances, setting trigger ports. An application that 
is UPnP-compliant has the ability to communicate with the Router, basically 
“telling” the Router which way it needs the firewall configured. The Router 
ships with the UPnP feature disabled. If you are using any applications that 
are UPnP-compliant, and wish to take advantage of the UPnP features, you 
can enable the UPnP feature. Simply select “Enable” in the “UPnP Enabling” 
section of the “Utilities” page. Click “Apply Changes” to save the change.
